Sorry to hear of the service issues experienced regarding your broadband, we appreciate the frustration and you raising this via the forums.
Do you experience the issues across all or specific games? Are these online multiplayer games? We have these tips available to help with broadband issues:
When running a speed test we would always recommend running this via a wired connection This can be completed using an ethernet cable via a PC or laptop and will allow us to see the speeds available at the Hub.
We do have the Connect App https://virg.in/connectapp that will allow you to scan your property to optimise the wireless network and if needed order pod's. Depending on your package these may be free but any package is eligible for these if needed.
